Frequently asked questions
Is my text private?
Nothing is uploaded. This tool runs entirely in your browser, so your data is processed on your own device and never sent to a server.
Is it free?
Yes — it is free with no sign-up, no watermark and no account-based quota. Your browser, device memory and the bench's stated file limits still determine how much it can process at once.
Which line transformations are available?
You can add line numbers, prefixes or suffixes, wrap each line, and apply the other operations shown in the selector.
